Moving now to the field of information retrieval, a major assumption is that the user is driven by an “information need.” Even when updated using Broder's “trichotomy” of web search types [1]} to include informational, navigational, and transactional searches, we still do not do justice to the complexities of human meaning and context. Such a model of human behavior abstracts a person to the level of its organismic interests. It is a caricature.
